Application tiled .l'anuary 27, 1921. Serial No. 440,398.

' To all whom it may concern."

Be it known that l, "CARL E. Bane, a citizen of the United States residing at Minneapolis, in the county. of ltlennepin and State of Minnesota, have invented a new and useful internal-Combustion Engine, of which the following is aspecification. This invention relates to engine cylinder constructions, an object of the invention being to provide a novel form of cylinder head to increase the efliciency of the engine by insuring the firing of the charge which enters the cylinder. i

A further object of the invention is to rovide a compartment or chamber, the walls of which are formed integral with the walls of the cylinder proper, the chamber providing a housing for the v spark plug points and adapted to receive a portion of the charge entering the cylinder, where the charge is fired. a.

A still further object of the invention is to rovide means for causing the charge en terlng the cylinder, to take a swirling motion within the compartment, to insure the intimate mixing of the elements of the I char e.

till

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and inthe detail of construct'on hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention hereindisclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing Figure 1 illustrates a fragmental longitudinal section view through a cylinder'and head constructed in accordance with the present invention.

Figure 2 illustrates a sectional View taken on line 2-2 of Figure 1'.

Figure 3 illustrates a transverse sectional view through a modified form of spark plug chamber. 1

Referring to the drawing in detail, the reference character 5 designates the cylinder of an internal combustion engine, the same being provided with the lateral bypass 6 through which the charge passes, on its travel to the interior of the cylinder.

llhe head which is indicated bythe refer-f ence character 7 and which forms the subject matter of the invention, is substantially dome shaped and is secured to the cylinder by means of the bolts 8.

'llhishead 7 is also provided with a bypass 9 in communication with the bypass 6, the upper extremity of the bypass 9 terminatlng in the valve chamber 10, in which operatesthe ball valve 11, the lower edge of the chamber 10 being cut away to provide a valve seat so that when the ball valve 11 1s m a position as indicated by Figure 1 of the drawlng, the by-pass 9 is closed, at its upper end.

' A, threaded plug 12 is positioned in the upper extremity of the chamber 10, and is provided with a central threaded opening 13 adapted to accommodate the adjusting screw 14;, which has its lower end disposed 1n spaced relation with the ball valve ll to restrict movement of the ball valve within the chamber 10, to vary the quantity of fuel pass ng through the chamber 10.

Disposed at the upper extremity of the cylinder and more articularly the head thereof, is a spherical chamber indicated at 15, which has communication with the intenor of the opening as by means of the opening 16, there being provided a threaded opening 17 in the upper portion of the chamber 15, to receive the usual threaded portlon of the spark plug, the sparking points thereof being indicated by the reference character 18 anddisposed within the m ber 15.

llhe chamber has communication with the chamber 10, through the passageway 19, the walls of which being formed tangent to the walls of the chamber 15 so that the charge entering the assageway 19 and the chamber 15, is caused to take a swirling motion within the chamber 15.

Arranged within the path of travel of the gas passing within the chamber 15, is a bame 20 which is formed integral with one of the walls of the passageway 19, and causes the charge to be thrown towards the center of the chamber 15 to insure an infinite mixture of the charge.

in the form of the invention as illustrated by Figure 3 of the drawing, the charge enters under the ball valve 11' where the same passes through the passageways 12, the charge passing into the spherical chamber 13', and since the divided charge is again mixed till ion

ltd

at a 14', lt'is obvious that mixture is provided.

In the operation of the device, assuming that the piston indicated at 21 is moving upwardly within the cylinder, it is obvious that aportion of the charge which has been drawn into the chamber 15, and upper portion of the cylinder, is compressed in the chamber 15, and when the spark plug, which has it pointsdisposed within the chamber fires, the charge within the chamber v15 is also fired with the result that the charge in the head is also fired to cause the operation of the piston. i 7

Having thus described the invention, what is claimed as n'ew'is: 7

An internal combustion engine including a cylinder having ahead formed with a an exceedingly rich point opposite the partitioning member ture in the presence of two witnesses.
